  • Ultra-High Split Frequency Separation: Routes 5–396 MHz upstream signals through the LOW port and 492–1800 MHz downstream signals through the HIGH port for ultra-high split cable broadband applications.
  • Low Signal Loss and Band Isolation: Maximum insertion loss is 1.5 dB on both paths. Isolation is at least 45 dB at 5–396 MHz, 40 dB at 492–1218 MHz, and 35 dB at 1218–1800 MHz.
  • Reliable ECT Connections: SCTE-compliant Eclipse Contact Technology F-ports provide increased contact surface area for lower contact resistance and dependable connections in 75-ohm coaxial systems.
  • Durable, Sealed Housing: Die-cast zinc-alloy construction, corrosion-resistant tin plating, and a fully soldered backplate provide RFI shielding. A 15 psi pressure seal helps prevent water ingress.
  • Surge Protection and Easy Mounting: All ports withstand multiple 6 kV ring-wave surges per IEEE C62.41 Category A3. Integrated mounting tabs and a heavy-duty ground block simplify installation, with operation from −40°C to +60°C.

Antronix DPA396-492 is a 75-ohm ultra-high split diplex filter designed to separate upstream and downstream frequency bands in cable broadband systems. Its LOW port passes the extended 5–396 MHz upstream band, while its HIGH port passes 492–1800 MHz downstream signals. Maximum insertion loss of 1.5 dB on either path helps preserve signal strength, while isolation between the bands supports reliable two-way communication.

Built for dependable service, the DPA396-492 features SCTE-compliant ECT F-ports, a corrosion-resistant tin-plated zinc-alloy housing, and a fully soldered backplate for RFI shielding. A 15 psi pressure seal helps resist water ingress, while integrated mounting tabs and a heavy-duty ground block support straightforward installation. The filter operates from −40°C to +60°C and provides 6 kV ring-wave surge withstand capability, with corrosion resistance tested to ANSI/SCTE-143 for 1,000 hours of salt-spray exposure.
